TRIPLEX MOTOR FOR STREET-RAILWAYS.

SPECIFICATION forming part of Letters Patent No. 365,273, dated June 21, 1887.

Application filed May .20, 1886.

To all whom, it may concern.-

Be it known that I, BENJAMIN O. POLE, a citizen of the United States, residing at Canr den, in the county of Camden, State of New Jersey, have invented certain new and useful Improvements in Triplex Motors for Street- Railways, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention consists in construction in and to the foot action; also in certain construction necessary to the driving-wheel aetion, so as to enable the driver of the motor to apply more or less power to the drivingwheels; and it consists in the construction of a friction-brake having certain useful functions.

The invention further consists in a means of preserving the foot actions from wear and tear of the streets and the dirt and dust of the same; also, in certain constructions of the feet, whereby they may be kept warm in winter, thereby preventing them from becoming balled, and thus unable to hold upon the ground; and, further, in providing them with calks, which may be sharpened in slippery weather; also, in constructions by which the flow of gas is made to first leave ahigh-press urc tank and thence into two pressure-regulators, from thence to a water-loeked gasometer, thence to an elastic bag, and thence to a gas engine, which is the motive power of the motor, and in constructions whereby the hi ghpressure gas is made to pass the before-mentioned pressure-regulators, and then to divide into two streams of gas, one, as hereinbelbre stated, to supply a gas-engine, and the other to supply the lights of the said gas-engine, as will hereinafter be set forth; also, in constructions whereby the feet will be maintained in good form and shape, notwithstanding they are distorted and compressed at each footstep of the motor; also, in a system of balancing the before-mentioned foot actions; also, in constructions of the friction-devices of the motor, which will allow of speedy adjustment of the friction-brake when the same may become worn; also, in a construction of a T- joint in the foot action to enable the foot to be placed squarely on the ground; the above construction being improvements on Letters Pat- Serial No. 202,771. (No model.)

Referring to the drawings, my triplex motor is provided with four driving-wheels, A, and these wheels are upon axles A A". The

axles carry chain sprocket-wheels (shown in tion-rod, D and this operates the plunger of the pumps E. In this construction of motor the pumps'E are in the front of the motor. The pumps E are two sets of pumps to pump water, and this water, water and glycerine, or oil is pumped over and over again to operate two hydraulic cylinders, F, of the motor. The pistons of these hydraulic cylinders F are connected with cross-heads F. The crossheads F are connected by conneetingrods F F to a foot action, Ft The foot action F is provided with a flat master-plate F. This plate F is to carry the rubber cushions F, F, and F of the foot action. The master-plate has a projection downward, F, through which passes the thrust-bolts F which are provided with the face plates F and F". These plates force onto therubber and make an elastic thrust in theaction of the foot. At the end of the bolt F is the plate with fiat hole F and through hole in the eye-plate is the bolt F. This bolt F is the foot of the motor, and has the prongs f f f factuall y four to each one foot. The bolt F passed through the rubber F, which is of the shape indicated by Fig. 3, and the holes shown byfffif allow the bolts F to be squeezed out of distaneesby the action of the motor walking or running; but upon the foot being lifted from the ground it will again come into its proper shape.

Upon the top of the master-plate F is the connection G, which holds the T-shaped end of the thrust-rod G of the foot action. Where there are two rods they will be G and G. This rod is connected at the top end by a clevis, G to a balanced beam, G This beam vibrates at g, and is connected by a cross-head, G to an air-cylinder H. At the end of the beam G is the counterbalance-weight G". The air-cylinderH is supplied with compressed air from the action of the main power of the motor, and the valve action (shown in dotted lines) is of the ordinary stop action known in the church-organ, and is placed into action by the stop-lever H. 5

At the side of the lever 11, and nearly inline therewith, is thedriving-lever I. This is connected with the hydraulic pumps E, and operates the supply of water to-the pumps through the valve E. In a line with this lever I is a brake-lever, the connections to the brake-shoes,

K, connected to the cylinder of a gas-engine for the purpose of keeping it cool, the warmer der L and the colder returning in at the bottom thereof, so that a circulation of the-water is maintained through its own well-known nature of movement due to heat.

Immediately in front of the water-tank is a tank, M. This tank is to receive a charge of gas under high pressure, and to use this gas in the motor it is-take'n out of the tank at the first tap immediately in front of the tank, and by the pipe m is conveyed to two T-couplings, mm. These connecting with stop-valves m m immediately underneath gas regulator devices m m. These have secondary taps m m, and then the pipes m m go into two T-couplings,

water being taken out of the top of the cylinm m, and these couplings supply the pipes m m, and the division in the supply ofgas at m is for the purpose that, as the cylinder of a gas-engine takes in a sudden suction of gas, it the lights for the gas-engine are on the same immediate supply as the cylinder, then the sudden suction will put these lights out. By the construction of the double regulators the high-pressure gas comes to a full stop at the regulators and is not affected by the gaseugines' action, so that after the gas passes the regulators mfim the two streams of gas are independent and each do their respective duties. The pipe at is led to the back part of the motor and is carried into the bottom of a water-locked gasometer, n. This gasometer n has the regular stand-pipe inside and delivers its regulated pressure gas to pipe n, and at a" this pipe enters pipe at, which is provided with the elastic gas-bag Nt It will be seen that the pipe it goes into the pipe in. This is so as to immediately take the regulated sup- .ply of city-pressure gas and yet be enabled to respond with-a rapid supply of plenty of gas from the gasometer a when necessary. The pipe m can be treated in the same manner as the pipe m and the supply of gas delivered at the pipes O, as shown in dotted lines.

The great difficulty in keeping the gasen- 'gine cylinder cool in winter time is an advantage to the motor. A pump will be supplied and a system of rubber pipes led down the thrust-rod G of the engine to a hot-water chamber, P, Fig. 19. This will be kept above the freezing-point by this means, and the foot action come down sharp cut, and will not ball by the ice and snow. The covering P is to prevent the dust from injuring the feet of the mo tor. The master-plate can be provided with points, as shown in Fig. 18.

The friction partof my invention is designed to enable the driver of the motor to place more or less powerinto the driving constrnctions of the motor; or, in other words,to give any desired force to the driving-wheels of the motor.

On the shaft G is the case B, and in the interior of this case is a projection, B, to which isabell-crank, B and. lever B". The end of the lever B has an eye, B forged onto it, and into this eye is another link, B, forged, making a chain connection. The end of the link B terminates in the clevis-jaws B on the sleeve B This sleeve B has the annular groove, B, connection to allow for amovement in and out on the shaft 0. The case B also is provided with the cleat B, and this cleat connects with the adjustable strap B". This strap passes roundawheel, B, which is keyed by a key, B, onto the shaft 0, so that the revolution of the shaft 0 is transmitted to the wheel B and to the case B only when the sleeve B is forced along the shaft 0. The connection B causes the link B and B to rise, so as to move the crank B. This crank is attached to the cleat Bfiand this cleat is bolted to the cover B, and the outer end of the crank B is attached to the strap B". This strap is wound around the wheel B, and the other end of the strap is attached to the cleat B" on the cover B, and the action of the crank B is to draw up tightly the strap, and by it tighten the shoes B on the wheel B. As the wheel B is keyed at B to the shaft 0, the tightening of the shoes B by the strap B, through the action of the beforementioned parts, causes the motion that is in the shaft 0 to be transmitted to the cover B, and by it to the chain-wheel A, which is attached to it. This strap B can be protected by asmall counter-shoe, B, and held by pin, as shown in Fig. 10.

Figs. 11 and 12 represent constructions in which wheel B in Fig. 12 is provided with a Vgroove construction, and likewise the shoe which touches upon the same.

In Fig. 11 the shoe B is provided with guideears I) b,'the center of the shoe I) being of a soft substance, for the purpose of replacement when worn out.

Figs. 11,13, and 14: represent attachments to the lever B, so that a wrench, B, can opcrate on the bell-crank B", and in that way it can be tightened up on the strap B.

The motor hereinbefore set forth is to be operated by a gas-engine, which runs along, notwithstanding the motor may be stopped, and accumulates a pressure of air and water-the air to operate a cylinder, which places the foot action on the ground, and the water to force along the motor. Two feet of like construction are in the motor, being a double or duplex action of or for traction. In this motor there is an additional point, whereby the triplex nature of the invention comes in play,

so that there are two feet for traction purposes and a perfect set of coupled driving-wheels operated by a friction device at the will of the operator,giving thetriplex motor three chances ot'traction, the cohesion of the driving-wheel construction being worth onefifth of the weight of motor for its traction-pull on a slippery rail, one-tenth of the weight on a slippery rail, and on a curve but onetwentieth. The duplex feet action of the motor of the traction is so regulated by the pressure which is given by the cylinder H that thetraclion will be steadily held at two thousand pounds; and it is possible in this system of motor to use instead of the gas-engine the following powers: Steam, electricity, either by taking up the power from a charged rail or by storage-battery, vacuumengine, high or low pressure compressed air, ammoniaeal gas, chloride of calcium, bisulphate of carbon, tank of hot water understeampressure to give off its steam for use on the journey, carbonic acid, compressed soda'ammonia, or petroleum -cngine, any of which powers can operate my motor.
